Online streaming services are turning down loud songs.

We all hate sudden changes in loudness - they're the #1 source of user complaints.

To avoid this and save us from being "blasted" unexpectedly, online streaming services measure loudness, and turn down music recorded at higher levels. We call this reduction the "Loudness Penalty" - the higher the level your music is mastered at, the bigger the penalty could be. But all the streaming services achieve this in different ways, and give different values, which makes it really hard to know how big the Loudness Penalty will be for your music...

Until now.

Simply select any WAV, MP3 or AAC file above, and within seconds we'll provide you with an accurate measurement of the Loudness Penalty for your music on four of the most popular music streaming services, plus a "ballpark" estimate for Apple Sound Check, which is used by Apple's radio streaming service.

What do these numbers mean?

Online streaming services measure loudness, and turn down loud music to avoid "blasting" listeners with sudden changes in loudness.

We call this level reduction the "Loudness Penalty" - the lower the LP numbers, the more your music will be turned down to match other songs.

For example, a Loudness Penalty of -2.4 on YouTube means your song will be played back 2.4 dB quieter than its original loudness.

Why are there different LP numbers?

Each streaming service chooses their own method of measuring loudness, and how loud the loudest songs should be played (the reference level). This means there is a slightly different Loudness Penalty for each service.

What have you got against loud music?!

Nothing! We love loud, aggressive genres as much as anyone else, but users complain about unexpected changes in loudness, and the streaming services want to avoid this.
